Measuring The Acute Physiological Effects Of Leptin In The Carotid Body, Richard Laurence Pye

Browse all Theses and Dissertations

Obesity is the healthcare crisis of our generation. Circulating levels of the adipokine leptin are proportional to adiposity and in addition to its role as a satiety factor leptin has been shown to have a host of pleiotropic effects. Among these effects is its role as a respiratory stimulant where it has been shown to have both whole body and central stimulatory effects on breathing. Porzionato et al. (2011) showed that leptin and leptin receptors are selectively expressed in the chemosensing type I cells of the carotid body. Carotid bodies are small chemosensitive organs that act as the primary peripheral …

The Guinea Pig Model For Organophosphate Toxicology And Therapeutic Development, Christopher Daniel Ruark

Browse all Theses and Dissertations

Organophosphates (OPs) are highly toxic insecticides and nerve agents that have been designed to inhibit the hydrolysis of acetylcholine by binding to the serine active site of acetylcholinesterase (AChE). They are one of the most common causes of human poisoning worldwide and are frequently intentionally used in suicides in agricultural areas. For this reason, there is a need for therapeutics to rescue those from intoxication. Obvious ethical concerns prevent humans from being subjected to OP exposure for therapeutic efficacy and safety testing. Therefore, animal surrogates for humans must be appropriately selected. A new paradigm, described herein, incorporating both in silico …

Strategies for improving student success are particularly important in high-demand fields like science, technology, engineering, and math (STEM). As the U.S. experiences a decline in skilled STEM workers and a growing number of racial/ethnic minorities, it is critical that more attention be paid to the college success of underrepresented populations majoring in STEM. While some strategies for increasing STEM student success have focused on social-psychological factors such as academic self-efficacy and resilience, little attention has been given to these factors among specific minority groups in STEM such as Black men. To extend the current literature, interviews with 27 Black male …
